Broadband signal frequency multiplier apparatus using dielectric resonator means

摘要

A frequency multiplier circuit is created by using a step recovery diode along with its signal source and reactive circuit to produce a comb of frequencies. This comb of frequencies is then applied to a dielectric resonator circuit for filtering all but the desired harmonic of the source. Correct positioning of the dielectric resonator on its parallel positioned input and output transmission lines, can be used to affect the phase of reflected signals to further enhance the signals which are reflected back to the step recovery diode thereby increasing the efficiency or further generation of harmonics of the desired frequency applied to the dielectric resonator and thus, output by the multiplier circuit. The multiplier frequency obtained is determined by the natural resonant frequency of the dielectric resonator chosen thereby providing a basic device which can be used as a source for many different output frequencies.
